Claims.

This invention relates to improvements in removable window sash construction and the primary purpose of this invention is to provide a removable sash construction for windows where- 5 by the window sash may be removed from the frame for the purpose of cleaning or washing.

A further object of this invention is to provide a removable window sash of the above mentioned character to be released from the window l0 frame by means of a movable vertical guide rail having edges and ends so constructed as to move the guide rail vertically as well as horizontally so that the guiding face will be moved out of engagement with the vertical contacting face of the window sash.

A still further object of this invention is to provide a movable guide rail adapted to be moved into and out of engagement with the window sash by means of a lever pivotally carried by the vertical window frame and having a lost motion connection with the guide rail.

A still further object of this invention is to provide locking means for the movable guide rail whereby the same may be held in its operative position so that the guiding face will engage the vertical contacting face of the window sash.

Other objects and advantages of the invention will become apparent during the course of the following description forming a part of this specication and in which,

Figure 1 is a top plan view of a Window sash construction embodying this invention, and illustrating the vertical guide rail in its operative position; v

Figure 2 is a top plan view of a Window sash construction showing one of the vertical frame members in cross-section to illustrate the movable guide rail in its released position whereby the window sash may be readily removed from the window frame;

Figure 6 is a view similar to Figure 4 with the lever in shifted position;

Figure 7 is a detail sectional view showing the wrench socket in the window stile; and

Figure 8 is a detail 'sectional View taken on 65 line 8 8 of Figure 7.

In the drawings wherein for the purpose of illustrating the invention and wherein like reference characters will be employed to designate like parts throughoutv the same, the reference character 6 will generally be employed to designate a window frame having vertical side rails 7, top and bottom rails 8 and 9 suitably grooved for connection to the vertical side rails 7. The sill rail 10 dependsY from the lower -ral 9 in the usual manner. i Y

Extending between the top and bottom rails 8 and 9 are guide rails 11 and 12 held in place by having the ends thereof received in grooves 13 extending transversely throughthe top and 8 bottom rails 8 and 9. Guide rail V12 is provided with a rib 14 which extends the entire length thereof while the guide rail 11 is provided with a similar rib 15,- said guide rail and rib only` extend downwardly from the top rail 8 to a position half the height of the window frame.

The guide rails 11 and 12 are held. in the vertical side rail 7 by means of front and back strips 16 and 17 secured to the vertical side rails 7 by nails or screws. The inner edges of the front and back strips 16 and 17 are closed by the guide rails 11 and` 12 and vertical strips 18 are interposed between the guide rails 11 and 12 and to the rear strip 17 for the purpose of guiding the window in the frame.

Slidably guided by the guide rails 11 and 12 are upperand lower window sashes 19 and 20 and window sashes 19 and 20 are counter-balanced by sash weights 2l and 22 respectively connected to the sash chains 23 and 24 passing `100 over a sash pulley 25. The sash weights 21 and 22 operate in the spaces formed by thevvertical side rails 7, front and rear strips 16 and 17 and guide strips 11 and l2.

The lower portion `of one of the vertical side frame members 7 may be provided with 'a movable guide rail 26 having a guide rib 27 similar to the guide ribs 14 and 15. Said guide rail 26 is slidably mounted between the front and rear Strips 16 and 17 as clearly shown in Figure 3 110 and is provided at its ends with bevelled portions 2S. The lower end 27 is adapted to be engaged in a bevelled groove 29 while the upper edge 28 is adapted to engage a bevelled end 30 of the upper guide rail 11 whereby vertical movement of the guide rail 26 will cause the same to move outwardly and away from the window sash frames 19 and 20.

Means is provided for moving the guide rail 26 and said means comprises a plate 31 secured to the inner side of the upper guide .rail 11 by means of screws 32. The metal plate 31 is prof vided with a central opening in which is journalled a shaft 33 having mounted on the. inner end thereof a lever 34 by means of a block 34a. The free end of the level` 34 is rounded or bevelled as at 35 so that the same will engage the upper edge of the guide rail 26 and force the' same home after it has been released. Connec ed to the free end of the lever 34 is a pin 36 to which is connected one end of a rod 37 while the opposite end of the rod is provided with a spherical member 38 for limiting the movement of the rod 3'? through an eyelet 39 carried by the inner wall of the guide rail 26. It will be noted that as the shaft 33 is rotated from the position shown in Figures 1 and 4, the rod 37 will be raised as shown in Figure 6 until the spherical end 38 engages the eye 39 whereby the guide rail 26 will be raised vertically and said vertical movement will cause the edge 38 on the upper end thereof to engage the lower edge 30 of the guide rail 11 to move the guide rail 26 laterally away from the window sash frames 19 and 20 as is illustrated in Figures 2 and 6. When the pivoted lever 34 is in the position shown in Figures 1 and 4, it engages a plate 40 secured to the upper end of the guide rail 26 by means of screws 41 in order to drive the guide rail 26 home to its seated position as shown in Figure 1.

The shaft 33 is provided with a key extension 42 as shown in Figure 8 so that the socketed end 43 of a wrench 44 may engage the socket 42 for the purpose of rotating the lever 34. The key extends into an opening 42a in the rail 11.

Before the lower guide rail 26 has been moved to its releasing position as shown in Figure 3, the upper window sash 19 should be moved downwardly to its limit as shown in Figure 2, both sash chains 23 and 24 being disconnected from the sashes and while the sash weights are raised, the sash chains are attached to the hooks 23a shown in Figures 2 and 3 to hold the weights in position until the sashes are returned to the window frame.

It is to be understood that the lower portions of each of the vertical guide rails 11 and 12 may be provided with movable guide portions and that other changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claims.
